The project is being led by Dr See Kye Yak, associate professor at Singapore Nanyang Technological University's School of Electrical and Electronic Engineering.
Most existing electrification inspection systems are based on ultrasonic, pulsed eddy current, and machine vision technologies, which require sensors and instruments installed on a dedicated inspection vehicle. However, the technology under development in Singapore uses radio frequency inductive coupling, meaning there is no direct electrical connection to the high-voltage electrification system and making it safe to use without affecting the normal operation of the train.
This means the system can be installed on standard vehicles, allowing it be used on passenger trains and enabling real-time monitoring of electrification assets, with the infrastructure being inspected every few minutes by a passing train.
